Eyes won't show correctly (Overlapping?) (Transparency Issue?)
Eevee treats transparent objects differently than Cycles. They are sorted from front-to-back per object and do not receive any screen space effects.

This is fast and works fine for many cases, but it is only approximate and gives incorrect results for some object shapes. For more accurate results, enable Alpha Hashed transparency in the material. With a sufficient number of samples to resolve the noise this gives accurate transparency.
